I loaded a total of 50 cartridges with 44.0 gr. of H-4198 powder, a 240 gr. Rem? jfp bullet,New R-P cases, COL of 2.505" wrong... see below, Full length sized and trimmed to 2.215" and Factory crimped. I only sent 5 rounds of each down range as I wanted to see any differences between primers. The only difference was the primer, in one half of the loads was Winchester WLR, in the others CCI 200. The Winchester loads chronied in at an average of 2235 fps for a 5 round group, the CCI loads chronied at an average of 2066 fps 5 round group, that makes a difference of 169 fps. The Winchester WLR are hotter than the CCI as evidenced by the target, although I must admit to liking the CCI group better! ;D. WLR group center is 1.2" high and .57" left while the CCI group is 1.79" low and .025" left. Load info came from Hodgdon website on line.
Others shot that day at 50 yards were Identical to the above info with EXCEPTION of Winchester Primers and Hornady 265 gr. jfp
1 Shot went a bit high, you can see the bottom of the bullet hole right above the Sq in the word square at the top of the target
I missed writing down the fps a couple times, but all targets had 5 rounds sent at 'em. And guys...don't hold me to the exact reading I have down, that all changes each time I use the On Target program, but the numbers are close enough to work off of.
. You'll notice also that the average fps is faster than what the data sheet indicated. I'll have another post upcoming regarding the 45/70 as soon as I can get enough info together to ask for your opinions. 8-7-2011 partly cloudy, 8-10 mph wind from the northwest, temps upper 70's-low 80's, low humidity, all equaled a good day at the range!

NOTE OAL length in the original post is incorrect, in another thread the OAL was pointed out, after measuring the rest of my reloads I have to say the proper OAL should be 2.55 rest of my reloads are 2.55-2.66 Hornady states max is 2.57
